I discussed two weeks ago with one of the judges that has seen Phragmipaphium Hane's Magic. He is one of the most skilled breeders anyone can think of, and for him it was sure that the plant was not a pure paph or a pure phrag. The chromosomes were those of a paph, but with some 'abnomalities' that were never explained - anyway it was in the early days, so chromosome counting was possible, to check if some satellite dna was around and could make up for a difference was out of question -
He told me that no paph parents could have done such an hybrid... The plant died some years later, but was growing quite vigorously before...
